Properly handle arrays for enabled_perf_events
Since the nova_config provider assumes that arrays are multi-str
configuration items, the enabled_perf_events would not be properly
configured if an array was provided. This resulted in idempotency issues
when [] was used as well as dropping values if ['cmt','mbml'] was
passed. This change ensures a comma seperated list is used for the
configuration value of enabled_perf_events.

The configuration for libvirt/enabled_perf_events requires a comma

seperated string for the value. The libvirt_enabled_perf_events parameter
